A Literature Review on Supramolecular Devices

Supramolecular device includes hydrogel and polymer manufactured by gelation or polymerization. Hydrogels are produced via chemical and physical gelation. Polymers are synthesized through photopolymerization, step-growth, and chain-growth polymerization. The supramolecular device possesses as the host to entrap the guest molecules via chemical, physical and physical-chemical microencapsulation. The present review article discusses the microencapsulation techniques, mechanism of gelation or polymerization, and different gelation or polymerization methods with given examples, such as gelatin, chitosan, and polyvinyl alcohol (PVA), and polyamide to act as the hosts for encapsulation.
